Cover Picture: Palladium‐Catalyzed Coupling of Aldehyde‐Derived Hydrazones: Practical Synthesis of Triazolopyridines and Related Heterocycles (Angew. Chem. Int. Ed. 45/2010)

Pharmaceutically active compounds … … and their intermediates require selective, efficient, and robust syntheses that utilize green chemistry principles. In their Communication on page 8395 ff., O. R. Thiel, M. Achmatowicz, and co‐workers describe a two‐step procedure involving selective palladium‐catalyzed carbon–nitrogen bond formation followed by a clean oxidative cyclization that affords access to a variety of bicyclic and tricyclic heteroaromatic scaffolds.
